[Condor-users] set a variable number of cores used

[Hermann Fuchs <hermann.fuchs@xxxxxxxxxxxxxxxx>]

Hello

I run into a tricky condor management question.
We acquired a few new workstations. These are usually in use during the
day and idle at night.
However, day usage would not need all resources, most of the resources
can be used by condor.
Each workstation has 6 cores, 4 of them could be used during the day and
all 6 cores during the night.
Simply suspending jobs on the other two cores does not work due to RAM
limitations.

Therefore we need the following:
During daytime use only 4 (of 6) cores (e.g. calculate only 4 jobs
simultaneously). During nights use all 6 cores.

Is there a way to do this?

Best regards,
Hermann
